Unless a patch causes a widespread massive issue with all machines, they won't pull it (just setting expectations, not making excuses)
Can you list a bit more info for these impacted machines and would you be willing to open a phone support case with a Microsoft engineer?
What version of Windows (XP, 7 home or pro?)
32bit or 64bit?
Are you seeing the exact same symptoms on all 50?
Is it with the same application? Appears to be Adobe in your screenshot? What Adobe products do they have installed?
